I just uploaded the plugin and it is workin in my test site. But when I installed it to my main site, it is not functioning. Both of the site has the same plugins used and theme used but i cannot see why it is not working.

thanks for your comment. Is it possible to see the plugin in action on http://www.accesscongo.com without being logged in? Have you tried turned on the debug mode? Most likely a selector needs to be changed to work with your theme...

i guess you need to be logged in to comment. I tried turning on the debug mode but it does not display also. The selectors used are i think the default selectors because it worked on the test site without any problem.
